Review request for Dolphin and Emmanuel Pescosta.


Description
-------

After https://git.reviewboard.kde.org/r/109180/, the main missing piece in the functionality around parent-child relationships that cannot be determined by parsing the URL is the removal or collapsing of expanded folders which have filtered children. This patch fixes it by removing the code that iterates over the filtered items from setExpanded() and slotItemsDeleted() to a new function removeFilteredChildren(), and making this function respect the parent-child relationships.

Diff: http://git.reviewboard.kde.org/r/109455/diff/


Testing
-------

Tried by browsing smb:, where collapsing a folder with filtered children did not work correctly before this commit. That works now; old and new tests pass.


Thanks,

Frank Reininghaus
